My forces are not enfeebled, I find no decay in my strength; my
provisions are not cut off, I find no abhorring in mine appetite;
my counsels are not corrupted nor infatuated, I find no false
apprehensions to work upon mine understanding; and yet they see
that invisibly, and I feel that insensibly, the disease prevails.
- Dr. John Donne, Devotions (X, Meditation)

The stomach is the only part of man which can be fully satisfied.
The yearning of man's brain for new knowledge and experience and
for more pleasant and comfortable surroundings never can be
completely met. It is an appetite which cannot be appeased.
- Thomas Alva Edison

The youth who follows his appetites too soon seizes the cup,
before it has received its best ingredients, and by anticipating
his pleasures, robs the remaining parts of life of their share,
so that his eagerness only produces manhood of imbecility and an
age of pain.
- Oliver Goldsmith

The ancients had a significant and truthful saying, that hunger
was the best sauce for supper.
- Rowland Hill

Seest thou how pale the sated guest rises from supper, where the
appetite is puzzled with varieties? The body, too, burdened with
I yesterday's excess, weighs down the soul, and fixes to the
earth this particle of the divine essence.
- Horace (Quintus Horatius Flaccus)
